ABSTRACT Aims and objectives To evaluate sinunasal diseases with the help of nasal endoscopy. To study efficacy of nasal endoscopy in diagnosing nasal pathology over clinical examination. To define medical and surgical functional endoscopic sinus surgery (FESS), management according to type of nasal pathology. To define applications of nasal endoscopy (biopsy, swab, epistaxis control, foreign body removal, rhinolith removal, follow-up). Materials and methods Total 100 patients were studied. Patients came with complaints of nasal blocking, nasal discharge, mass in nasal cavity, bleeding etc, included in study. Pre-endoscopic assessment was carried out like history, examination, investigation. Endoscopic was done after consent under necessary anesthesia. Endoscopy was done using 0 and 30° endoscope with three standard passes. Result Total 100 patients were studied. Male to female ratio was 1.8:1. Out of 100 patients maximum number of patients had chronic sinusitis on nasal endoscopy examination (22); followed by nasal polyp (27) and deviated nasal septum and epistaxis (10). Nasal endoscopy was an excellent diagnostic aid in condition like epistaxis, nasal mass, nasal obstruction, foreign body, nasopharyngeal tumor. Conclusion Diagnostic nasal endoscopy offers high diagnostic accuracy in patient with sinonasal complaints. Diagnostic nasal endoscopy is gold standard tool in patient having sinonasal complaints. It has high accuracy due to vision control, has less bleeding, minimal complication, and early postoperative recovery. It is a good tool for diagnosing anatomical variation.

AbstractThe authors have used the nasal endoscope for the precise identification of pathological abnormalities of the nasal septum in relation to the lateral nasal wall including the osteo-meatal complex and in its ultraconservative management. The aim of the study was to compare the efficacies of endoscope-aided septoplasty (EAS) over traditional septoplasty (TS) in treating the pathological septum and turbinates, performed in 30 cases each. The subjective assessment was carried out by visual analogue scores and objective assessment by nasal endoscopy. This study demonstrates the superiority and limitations of the endoscopic approach in managing a deviated nasal septum and the turbinates. The endoscope-aided technique was found to be more effective in relieving the contact areas and nasal obstruction (p = ≤0.05). The authors advocate a combined approach – an endoscopic approach for inaccessible posterior deviation and the conservative traditional technique for accessible anterior deviation of the nasal septum.

Background/Aim. Chronic rhinosinusitis (CRS) is one of the most common chronic conditions that is diagnosed on the basis of the condition symptoms, nasal endoscopy and computed tomograhpy (CT) of the nose and paranasal sinuses. There are two forms of CRS: CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). The aim of this paper was to determine if there is a correlation between the symptoms, nasal endoscopy and CT in patients with CRSsNP. Methods. The study included 110 patients with CRSsNP. The intensity of the symptoms assessed on the visual analogue scale (VAS) and the condition of nasal mucosa and the presence of nasal secretion was estimated by endoscopic examination of the nose while CT was used to determine the Lund-Mackay (LM) score values. Pearson?s coefficient of correlation was used for statistic data processing. Results. The severity of the disease as a whole (r = 0.509) and nasal discharge (r = 0.562) moderately correlated with CT. Nasal congestion (r = 0.354) and the reduction of loss of smell (r = 0.324) mildly correlated with CT, while facial pain/pressure (r = 0.218) had a very weak correlation with CT. The severity of the disease as a whole (r = 0.717) and nasal discharge (r = 0.821) strongly correlated with nasal endoscopy. Nasal congestion (r = 0.525) had a moderate correlation with nasal endoscopy while facial pain/pressure (r = 0.345) and the reduction of the loss of smell (r= 0.394) had a mild correlation with nasal endoscopy. A moderate correlation was found between nasal endoscopy and CT (r = 0.630). Conclusion. The severity of the disease as a whole and nasal discharge have more significant correlations both with nasal endoscopy and CT in relation to the correlations between other symptoms and nasal endoscopy, as well as CT. More significant correlations between the symptoms and nasal endoscopy in relation to the correlations between the symptoms and CT and the existence of a moderate correlation between nasal endoscopy and CT, enable a lesser use of CT diagnostics and only in precisely defined situatiations.

Full textAbstract:
Background: Epidemiological studies on chronic rhinosinusitis with nasal polyps are scarce and mostly based on questionnaires. Data obtained with such approaches can be unreliable, thus endoscopy is a prerequisite for an accurate estimate of the prevalence of nasal polyps. The objective of this study was to establish the frequency of nasal polyps in Northern Portugal, using nasal endoscopy in cadavers from a District Hospital. Methods: The cadaver specimens deposited in the mortuary room of the hospital, every early morning on week days, from December 2012 to August 2013, were submitted to a systematic endoscopic examination of both nasal cavities, using a 25°, 2.y mm rigid endoscope from R.Wolf®. A review of the medical record of the cadavers was done, to search for cause of death, co-morbidities and past ENT history. Results: A group of 200 consecutive Caucasian cadaver specimens were analyzed, 83 women and 117 men, with a mean age of death of 77.23 ± 12.29 years (range 34-97). The prevalence of nasal polyps was 5.5% (95% confidence interval, 2.34-8.66). No statistically significant association between the studied clinical variables (sex, allergic rhinitis, lower respiratory diseases and smoking) and the presence of nasal polyps was identified. Conclusion: The study provides the first endoscopic based epidemiological data on nasal polyps in Portugal, showing a prevalence for old age group in accordance with previous studies in Europe.

AbstractBackgroundNasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery.ObjectiveTo evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery.MethodsA pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22-item Sino-Nasal Outcome Test questionnaire and nasal endoscopy.ResultsPatients in the mupirocin nasal lavage group had lower nasal endoscopy scores post-operatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better Sino-Nasal Outcome Test scores at one month compared to the group without mupirocin.ConclusionNasal lavage with mupirocin seems to yield better outcomes regarding patients’ symptoms and endoscopic findings.

Aim: To compare the precision,efficacy and complication of nasal endoscopic assisted management of epistaxis with headlight assisted nasal packing.Materials and Methods: Two groups of twenty patients each were placed randomly in Group A and Group B. Patients in Group A were managed with headlight assisted nasal packing and Group B patients were managed with nasal endoscopic assisted control of epistaxis.Results: Exact site of bleeding was located in 90% patients of Group B. All patients in Group A complained of dry mouth(100%), halitosis in 6 (30%) patients, 12 (60%) patients had headache and discomfort,7(35%) patients had epiphora. There was no complication in Group B.Conclusions: Epistaxis is a common ENT emergency and routine blind hasty nasal packs should be avoided. Nasal endoscopes should be routinely used to identify site of bleeding and cauterisation of the targeted area should be done gently with least collateral damage to healthy mucosa. Good and easy control with less complications and no admissions are all possible with the wonder tool called “ nasal endoscope”.International Journal of Human and Health Sciences Vol. 03 No. 03 July’19.

Objective To study if nasal endoscope can be a reliable tool in assessing patients with allergic rhinitis. Materials and Methods A prospective study. Patients who were diagnosed with allergic rhinitis underwent a nasal endoscopic examination performed by two physicians blinded to the scoring of each other. A correlation was made among symptom severity, endoscopic findings, and interrater variability. Results Ninety patients were included in the study: 34 patients had mild disease and 56 had moderate-to-severe allergic rhinitis according to the Allergic Rhinitis and its Impact on Asthma guidelines. Increases in mucosal edema and bluish discoloration were predictive of the severity of allergic rhinitis disease (p < 0.05). The presence of nasal secretions was not predictive of allergic rhinitis. Interrater reliability was fair for mucosal edema, moderate-to-almost perfect for the rest of the endoscopic findings. Conclusion Nasal endoscopy may reveal signs that are predictive of the severity of allergic rhinitis. A detailed checklist is needed for the nasal endoscopic examination to decrease interrater variability.

Nasal obstruction is common in children, and is often attributed to adenoid enlargement. This prospective study was performed to determine whether routine nasal endoscopy is of value for children undergoing surgery for nasal obstruction. Forty-eight children aged two to nine years undergoing adenoidectomy, and six normal controls, were examined under general anaesthesia with a 4 mm rigid endoscope. A video of the endoscopy was subsequently assessed independently by an observer blinded to the original findings and the presence of nasal symptoms.The endoscopist and independent assessor were in agreement regarding 86 per cent of the findings. Three quarters of the children had abnormalities on endoscopy in addition to enlarged adenoids, and in 23 per cent these were potentially of major clinical significance (unsuspected foreign body, gross septal deviation, gross hypertrophy of the turbinates). Endoscopy produced no post-operative complications and was possible in children as young as two years of age, without decongestants.Nasal endoscopy is a safe, objective and useful means of identifying potentially significant abnormalities in children with nasal obstruction.

Full textAbstract:
OBJECTIVES: Although endoscopy has been shown by a few authors to be a valuable tool for the diagnosis of chronic rhinosinusitis, its true role in the evaluation of the patient with chronic rhinosinusitis has not been elucidated. The current definition of chronic rhinosinusitis is a symptom-based definition, and objective testing such as endoscopy or computed tomography (CT) is not included. However, the current treatment paradigm for chronic rhinosinusitis is dependent on the definition for diagnosis. Patients are treated with 4 weeks of antibiotics and decongestant/antihistamines/steroids based on the definition. This study aims to evaluate in a prospective fashion the place of endoscopy in the diagnosis of chronic rhinosinusitis. STUDY DESIGN: A group of 78 patients meeting the definition of chronic rhinosinusitis were subjected to same-day endoscopy and CT scanning. RESULTS: Seventeen (22%) of 78 patients had positive endoscopic and CT results. There were 20 (26%) of 78 patients with negative endoscopic and positive CT results. Six (8%) patients had positive endoscopic and negative CT results, and 35 (45%) had negative endoscopic and negative CT results. Overall, 37 (47%) patients had positive CT results, and 41 (53%) patients had negative CT results. Endoscopy showing the presence of purulence, nasal polyps, or watery congested mucosa correlated well with CT results. Negative endoscopy correlated with CT results in 65% of patients. CONCLUSION: The use of endoscopy to corroborate the diagnosis in nonpolypoid or nonpurulent rhinosinusitis in previously unoperated patients is questioned. Patients who meet the subjective definition of chronic rhinosinusitis should have a high degree of sensitivity and specificity with endoscopy or CT. The fact this is not the case questions the accuracy of the definition and the treatment paradigm. SIGNIFICANCE: According to this study, positive endoscopic results correlated well with CT, and negative endoscopic results correlated in 71% of patients with negative CT results.

A hipertrofia de adenóide promove uma diminuição do espaço livre da nasofaringe e se constitui em uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico desta condição, os mais precisos são a endoscopia nasal e a ressonância magnética, por permitirem a visualização da nasofaringe em três dimensões. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. Torna-se, portanto, de grande importância, a verificação da eficiência deste método de diagnóstico. Este trabalho foi realizado com o objetivo de determinar a eficácia da radiografia cefalométrica lateral no diagnóstico da hipertrofia de adenóide, pela comparação deste método com a endoscopia nasal. Foram avaliados 30 indivíduos (7 a 12 anos) sem história prévia de cirurgia otorrinolaringológica. Todos fizeram um exame de endoscopia nasal e uma radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe, e nas radiografias, a menor dimensão ântero-posterior livre da nasofaringe. Os valores encontrados pelos dois exames se mostraram fortemente correlacionados (r = ? 0,793, p-valor < 0,01). Em seguida, foram realizados os testes de validade e confiabilidade para o diagnóstico radiográfico. Para isso, foram considerados portadores de hipertrofia severa de adenóide, os pacientes que apresentaram, na endoscopia, obstrução da nasofaringe igual ou superior a 75% e, nas radiografias, o menor diâmetro antero-posterior da nasofaringe igual ou inferior a 5 mm. O exame radiográfico teve uma sensibilidade de 75%, especificidade de 86,3%, valor preditivo positivo de 66,7%, valor preditivo negativo de 90,4% e a exatidão foi de 83,3%. A radiografia cefalométrica lateral, então, se mostrou um exame eficiente para o diagnóstico da hipertrofia de adenóide, o que foi comprovado pela forte correlação entre os seus resultados e os da endoscopia nasal, que é considerado o exame padrão-ouro para o diagnóstico desta condição.

Este trabalho teve como objetivos a avaliação da cavidade nasal, através de rinoscopia, de cães portadores de afecção nasal crônica, identificando o tipo e a localização das lesões, correlacionando-as com os achados clínicos e radiográficos; verificar a epidemiologia segundo a raça, idade, peso e sexo dos; e definir o resultado qualitativo da biópsia. Foram utilizados 38 cães com sinais clínicos e alterações radiográficas compatíveis com afecção nasal crônica. Sobre a epidemiologia das afecções nasais, tivemos maior ocorrência de cães sem raça definida (SRD), adultos, macho, de porte médio e grande. As alterações mais encontradas em cavidade nasal foram as tumorais, sendo a afecção de maior ocorrência o TVT, representado em sua maioria pelo SRD adulto e macho, seguido de neoplasia de origem mesenquimal, neoplasia de origem epitelial, pólipo, rinite crônica, corpo estranho e aspergilose. A biópsia guiada por rinoscopia foi efetiva, com exceção dos tumores de origem mesenquimal. A rinoscopia neste estudo comprovou ser um meio diagnóstico efetivo, não invasivo complementar aos exames físico e radiográfico, que permite, pela técnica anterógrada associada à retrógrada, ampla visibilização da cavidade nasal, escolha do local de biópsia e colheita de material para cultivo, e em casos de corpos estranhos permite sua remoção, servindo como método diagnóstico e terapêutico.The aim of this study was to evaluate the nasal cavity of dogs, presented with chronic nasal disease, through rhinoscopy. In addition to checking the reliability of nasal biopsy results, rhinoscopy was used to identify the type and location of lesions and to relate them to the clinical and radiographic findings. Furthermore, we also gathered epidemiology data related to breed, age, weight and gender. For the purpose of this study we used 38 dogs that presented clinical signs and radiographic alterations compatible with chronic nasal disease. Regarding the epidemiology, the highest incidence of nasal diseases was noticed in mixed breed dogs. Also, nasal disease was more frequent in adult, male, large or medium sized dogs. The majority of nasal diseases were due to tumors, and in this regard the transmissible venereal tumor (TVT) was the most frequent and was mainly diagnosed in mixed breed, male, adult dogs. Mesenchymal neoplasia were the second most frequent alteration of the nasal cavity, followed by, epithelial neoplasia, polyps, chronic rhinitis, foreign bodies and aspergillosis. Rhinoscopy guided biopsy proved to be effective except in the case of mesenchymal tumors. The results of this study prove that rhinoscopy is an effective non-invasive diagnostic tool, which complements physical and radiological examination. Moreover, this study also shows that the association of anterior and posterior rhinoscopy techniques, allow for a wide visualization of the nasal cavity and determination of the biopsy location and collection of samples for culture. In additional, rhinoscopy is a useful tool for diagnosis and removal of foreign bodies.

Rinossinusite é uma causa freqüente de febre em pacientes internados em Unidade de Terapia Intensiva. Seu diagnóstico é muitas vezes tardio por causa da escassez de sinais clínicos e pode levar a complicações como meningite, pneumonia e sépsis. A severidade destas complicações impõe busca ativa do foco infeccioso sinusal, quando existe febre sem foco determinado. A tomografia computadorizada é o exame padrão ouro para esta investigação. Estudos demonstraram, porém, a ocorrência freqüente de rinossinusite detectada em exames radiológicos sem, no entanto, apresentar correlação com infecção sinusal. A endoscopia nasal é um método que permite avaliar as cavidades nasais e, em especial, a região do meato médio e recesso esfenoetmoidal. Esta habilidade tornou a endoscopia nasal um exame fundamental para a avaliação de pacientes com suspeita clinica de rinossinusite. O objetivo deste estudo é avaliar a eficácia da endoscopia nasal como método diagnóstico de rinossinusite em pacientes de terapia intensiva. Trinta pacientes consecutivos, internados em unidades de terapia intensiva, no período de Junho de 2003 a Agosto de 2006, apresentando quadro clínico e tomográfico sugestivo de rinossinusite foram submetidos a endoscopia nasal. Foram incluídos apenas pacientes com indicação de drenagem cirúrgica como modalidade terapêutica, e este é o método de confirmação diagnóstica de rinossinusite adotado. A endoscopia foi realizada antes da drenagem cirúrgica avaliando-se presença de edema e rinorréia em meato médio e recesso esfenoetmoidal. Foi aplicada anestesia e vasoconstrição tópica das fossas nasais, meatos médios e recessos esfenoetmoidais antes da avaliação endoscópica. Os resultados da endoscopia nasal não interferiram na terapêutica adotada para cada paciente, sendo esta determinada pelos intensivistas da Disciplina de Emergências Clinicas, em conjunto com otorrinolaringologistas do Departamento de Otorrinolaringologia do Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo. Dentre os 30 pacientes com suspeita de rinossinusite incluídos neste estudo, 21 apresentaram confirmação diagnóstica por meio de drenagem cirúrgica. No diagnóstico da rinossinusite a tomografia computadorizada mostrou sensibilidade de 97,3% e especificidade de 16,2%. Na endoscopia nasal encontramos sensibilidade de 76,1% e especificidade de 61,2%. Na presença de edema, a endoscopia apresentou sensibilidade de 85% e especificidade de 32%. No diagnóstico da rinorréia a sensibilidade foi de 67,6% com especificidade de 90,4%, e acurácia de 85%. Concluímos que a endoscopia nasal é um método eficaz para o diagnóstico de rinossinusite em pacientes de terapia intensiva, especialmente na presença de rinorréia.Rhinosinusitis is a frequent cause of fever in Intensive Care Unit (ICU) patients. Diagnosis is sometimes delayed because of lack of clinical signs and it may lead to complications such as meningitis, pneumonia and sepsis. The severity of these complications requires active search for the sinusal infectious focus in the presence of fever of undetermined cause. Computed tomography scan is the gold standard for such investigation. However, studies have demonstrated the frequent occurrence of radiological rhinosinusitis with no correlation with sinusal infection. Nasal endoscopy is a method that enables the assessment of nasal cavities, specially the region of middle meatus and sphenoethmoid recess. This fact has transformed nasal endoscopy into a fundamental exam to assess patients with clinical suspicion of rhinosinusitis. The purpose of the present study was to assess the efficacy of nasal endoscopy as a diagnostic method for rhinosinusitis detection in ICU patients. From June 2003 to August 2006, thirty consecutive patients hospitalized in the ICU who presented clinical picture and tomography results suggestive of rhinosinusitis were submitted to nasal endoscopy. We included only patients with indication of surgical drainage as management option, which was the adopted diagnostic confirmation of rhinosinusitis. Endoscopy was performed before surgical drainage to assess the presence of edema and rhinorrhea in the middle meatus and sphenoethmoid recess. We used anesthesia and topical vasoconstriction of nasal fossa, middle meatus and sphenoethmoid recess before the endoscopic assessment. The results of nasal endoscopy did not interfere in the therapy prescribed to each patient, who was determined by the Intensivists of the Discipline of Clinical Emergency, together with the Otorhinolaryngologists of the Department of Otorhinolaryngology, Hospital das Clinicas, Medical School, University of Sao Paulo. Among the 30 patients with suspicion of rhinosinusitis included in the study, 21 presented diagnostic confirmation through surgical drainage. Computed tomography showed sensitivity of 97.3% and specificity of 16.2% for the diagnosis of rhinosinusitis. In the presence of edema, endoscopy showed sensitivity of 85% and specificity of 32%. In the diagnosis of rhinorrhea, sensitivity was 67.6% and specificity was 90.4%, and accuracy was 85%. We concluded that nasal endoscopy is an effective method for the diagnosis of rhinosinusitis in intensive care unit patients, especially in the presence of rhinorrhea.

Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth
breathing. The accurate diagnosis of this alteration is important for proper
therapeutic planning. As a consequence, studies have been developed in order to
provide information about the procedures that can be used for the diagnosis of
pharyngeal obstruction. Objective: Verify the correlation between
nasopharyngoscopy and cephalometric exams in the diagnosis of pharyngeal tonsil
hyperplasia. Material and Methods: 55 children took part in this study, 30 girls and 25
boys, aged between seven and 11. The children were submitted to
nasofibropharyngoscopic and cephalometric evaluation to determine the grade of
nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5%
significance level was used to verify the correlation of these exams. Results: In
nasopharyngoscopy, most children showed hyperplasia of the pharyngeal tonsil
grades 2 and 3, followed by grade1. In cephalometry, most children showed
hyperplasia of the pharyngeal tonsil grade 1, followed by grade 2. A regular positive
correlation was observed in the correlation between the exams. Conclusion: It was
concluded that the evaluation of the pharyngeal tonsil hyperplasia can be carried out
by fiberoptic nasopharyngoscopy and cephalometry, as these examinations present
a regular positive relation. However, it was found that cephalometry tends to
underestimate the size of the pharyngeal tonsil in relation to nasopharyngoscopy.A hiperplasia de tonsila faríngea é uma das principais causas de respiração oral. O diagnóstico preciso desta alteração é importante para o correto planejamento terapêutico. Em vista disso, estudos têm sido desenvolvidos a fim de fornecer subsídios quanto aos procedimentos que podem ser utilizados para o diagnóstico de obstrução faríngea. Objetivo: Verificar a correlação entre os exames de nasofibrofaringoscopia e cefalometria no diagnóstico de hiperplasia de tonsila faríngea. Material e Métodos: Participaram deste estudo 55 crianças, 30 meninas e 25 meninos, com idades entre sete e 11 anos. As crianças foram submetidas à avaliação nasofibrofaringoscópica e cefalométrica para a determinação do grau de obstrução da nasofaringe. Para verificar a correlação entre esses exames foi utilizado o coeficiente de correlação de Spearman ao nível de significância de 5%. Resultados: Na nasofibrofaringoscopia a maioria das crianças apresentou hiperplasia de tonsila faríngea graus 2 e 3, seguidas de grau 1. Na cefalometria a maior parte das crianças apresentou hiperplasia de tonsilas faríngeas grau 1, seguida de grau 2. Na correlação entre os exames, evidenciou-se correlação regular e positiva. Conclusão: A avaliação da hiperplasia de tonsilas faríngeas pode ser realizada pela nasofibrofaringoscopia e pela cefalometria, pois estes exames apresentam uma relação regular e positiva. No entanto, verificou-se que a cefalometria tende a subestimar o tamanho da tonsila faríngea em relação à nasofibrofaringoscopia.

O propósito desta pesquisa foi avaliar, neste grupo de indivíduos, se ocorreram mudanças no padrão respiratório e na porcentagem do espaço aéreo livre bucofaringeano e nasofaringeano, bem como, se existia alguma relação entre a resistência nasal total e o espaço livre da bucofaringe e da nasofaringe, e entre os dados obtidos pela visão endoscópica clínica e o programa de análise de imagem da via aérea superior, após o tratamento ortopédico com o aparelho bionator de Balters. A amostra constou de 13 pacientes leucodermas, do sexo feminino e masculino, na faixa etária de 8 a 12 anos, com dentadura mista e má oclusão de Classe II divisão 1ª de Angle, do Departamento de Clínica Infantil da Faculdade de Odontologia de Araraquara (UNESP) e que não tinham sido submetido a tratamento ortodôntico. A resistência nasal foi avaliada, por meio da rinomanometria anterior ativa, já a bucofaringe e a nasofaringe foram avaliadas, por meio da nasofibroscopia. Para calcular o espaço aéreo total e livre bucofaringeano e nasofaringeano foi utilizado o programa UTHSCSA desenvolvido pelo Departament of Dental Diagnostic Science at The University of Texas Health Science Center. As médias e o desvio padrão de cada variável estudada foi obtida utilizando o teste t de Student ou de Wilcoxon.
The aim of this work was to evaluate the occurrence of changes in the respiratory pattern; in the free buccopharyngeal and nasopharyngeal airspace, if there was any relation between the total nasal resistance and the free buccopharyngeal and nasopharyngeal airspace, and if there was any relation between the data obtained by the clinical endoscopic view and the image analysis software of the upper airway after orthopedic treatment with Balters' bionator in this group of individuals. The sample was composed of 13 patients Caucasian descendents, both male and female between 8 and 12 years old, with mixed denture and Angle Class II Division 1 malocclusion, from the Infant Clinic Department of Araraquara School of Dentistry (UNESP), and that had not been submitted to orthodontic treatment. The nasal resistance was measured by active anterior rhinomanometry, and the bucopharynx and nasopharynx were measured by nasofibroscopy. In order to calculate the total and the free buccopharyngeal and nasopharyngeal airspace, it was analised the nasofibroscopy image using the software Image Tools, developed by the Department of Dental Diagnostic Science at The University of Texas Health Science Center. The averages and standard deviation of each variable studied were obtained using the Student-t test or the Wilcoxon test.

INTRODUÇÃO: Apesar do índice de sucesso da cirurgia da ligadura ou cauterização da artéria esfenopalatina, para o tratamento da epistaxe severa, ser maior que 95%, a falha pode variar de 2% a 10%. Algumas variações anatômicas na parede lateral do nariz são relatadas, sendo referentes à localização do forame esfenopalatino (FEP), à presença de um forame acessório, à ramificação das artérias e à dimensão e morfologia do FEP. A variação anatômica dessa região assim como a escassez de estudos endoscópicos mostrando pontos de reparo para o encontro da artéria esfenopalatina e seus ramos podem justificar a falha cirúrgica em alguns casos, assim como a dificuldade técnica encontrada por alguns autores. OBJETIVO: Descrever a anatomia da região do FEP na parede lateral do nariz e as possíveis variações anatômicas, durante a dissecção endoscópica em cadáveres, e observar as possíveis diferenças entre os achados anatômicos, o gênero (masculino/feminino) e o grupo étnico/racial, assim como a simetria entre as fossas nasais. CASUÍSTICA E MÉTODOS: Estudo anatômico prospectivo realizado de setembro de 2006 a janeiro de 2007. A região do FEP de 61 cadáveres frescos (122 fossas nasais) foi cuidadosamente dissecada, sob visibilização endoscópica. Prevaleceram os cadáveres do sexo masculino (75%) e grupo étnico/racial pardo, seguidos de negros e brancos. Foram observados a presença da crista etmoidal da lâmina perpendicular do osso palatino, a localização dos forames esfenopalatino e acessório, o número de ramos arteriais emergentes pelos forames e a distância dos mesmos à espinha nasal anterior. Os dados foram analisados em relação ao gênero, grupo étnico/racial e simetria entre as fossas nasais do mesmo cadáver. Foi, ainda, avaliada a predição da presença do forame acessório em relação ao número de ramos arteriais emergentes através do FEP, à localização do FEP e à distância do FEP à espinha nasal anterior. RESULTADOS: A crista etmoidal esteve presente em 100% dos cadáveres, sendo anterior ao mesmo em 98,4% das vezes. A localização mais freqüente do FEP foi a região de transição do meato médio e meato superior (86,9%). A distância média do FEP e do forame acessório à espinha nasal anterior foi respectivamente de 66mm e 67mm, com desvio padrão de 5,3 e 4,7mm. O forame acessório esteve presente em 9,83% dos casos. Um único tronco arterial emergia através do FEP em 67,2% das vezes e em 100% dos forames acessórios. A análise da prevalência das variáveis estudadas em relação ao gênero e grupo étnico/racial não mostrou diferenças estatisticamente significantes (p<0,05). A análise da simetria mostrou concordância boa a excelente em relação à localização do FEP (índice Kappa 0,71/ p<0,001); concordância pobre em relação ao número de ramos arteriais emergentes através do FEP (índice Kappa 0,22/p=0,03) e ausência de concordância estatisticamente significante em relação à presença de forame acessório (p=0,53). Nenhuma das variáveis de interesse apresentou associação estatisticamente significante (p>0,05) que permita predizer a presença do forame acessório. CONCLUSÕES: Existem variações anatômicas na parede lateral do nariz que devem ser levadas em consideração para o sucesso do tratamento cirúrgico endoscópico da epistaxe severa.INTRODUCTION: Even though the success rate of sphenopalatine ligation is greater than 95%, some authors have reported some difficulties in isolating those arteries during endoscopic surgical procedure. The failure rate of the sphenopalatine artery ligation or cauterization may vary from 2% to 10%. Some anatomical variations on the nose lateral wall are reported, with reference to the sphenopalatine foramen (SPF) location, the presence of an accessory foramen, arteries ramification and SPF dimension and morphology. Anatomical variation of the region, as well as scarcity of endoscopic studies showing landmarks to find the sphenopalatine artery and its branches may justify surgical failure. OBJECTIVE: The purpose of this study was to describe the anatomy of SPF region and possible anatomical variations, during the endoscopic cadaver dissection and to observe the symmetry between nasal sides and the relationship to gender and racial group. CASUISTICS AND METHODS: It is a prospective anatomical study developed from September, 2006 to January, 2007. The SPF of 61 fresh cadavers (122 nasal fossae) was carefully endoscopic dissected. Male (75%) and mixed race cadavers prevailed. Presence of ethmoidal crest, location of sphenopalatine and accessory foramens, number of arterial branches emerging through foramens and distances from the foramens to anterior nasal spine were observed. Data were analyzed in relation to gender, racial group and symmetry of the same cadaver. Prediction of the presence of accessory foramen was evaluated in relation to number of arterial branches emerging through SPF, SPF location and distance from the SPF to the anterior nasal spine. RESULTS: Ethmoidal crest was present in 100% of cadavers, being anterior to the SPF in 98.4% of times. The most frequent SPF location was the transition region of middle and superior meatus (86.9%). Mean distance from SPF and accessory foramen to anterior nasal spine was 6.6cm and 6.7cm, respectively. Accessory foramen was present in 9.83% of cases. A single arterial stem emerged through the SPF in 67.2% of times, and 100% through accessory foramens. The prevalence analyses showed no differences statistically significant (p>0,05) between gender and racial group. The symmetry analyses showed a strong conformity (Kappa index 0,71/p<0,01) between nasal fossae in relation to the SPF location; and a poor conformity (Kappa index 0,22/p=0,03) in relation to the number of arterial branches emerging through the SPF. There was no statistically significant conformity between nasal fossae and the presence of accessory foramen (p = 0,53). None of the variables of interest presents any statistically significant (p>0,05) association with the presence of the accessory foramen. CONCLUSIONS: Anatomical variations in the lateral nose wall exist, and should be taken into account, for a well-succeeded endoscopic surgical treatment of severe epistaxis.

Full textAbstract:
Introdução: A aplicação de Pressão Positiva Contínua nas Vias Aéreas Superiores (CPAP) durante o sono é o padrão ouro no tratamento da Apneia Obstrutiva do Sono (AOS) e foi primeiramente descrito utilizando uma máscara nasal. No entanto, na prática clínica a máscara oronasal é comumente. Este estudo foi desenhado para determinar os efeitos agudos da mudança de rota de fluxo do CPAP de nasal para oronasal e oral na patência da via aérea superior durante o sono em pacientes com AOS. Nós hipotetizamos que a pressão transmitida pelo compartimento oral da máscara oronasal pode comprometer a eficácia do CPAP no tratamento da AOS por empurrar a língua posteriormente. Métodos: Dezoito pacientes (idade 44 ± 9 anos, índice de massa corpórea de 33,8 ± 4,7 kg / m², índice de apneia-hipopneia 49,0 ± 39,1 eventos/hora) dormiram com máscara oronasal customizada com dois compartimentos (nasal e oral) selados e independentes conectados a uma válvula multidirecional. O sono dos pacientes foi monitorizado pela polissonografia e induzido por baixas doses de midazolam (3,1 ± 2,2 mg). O CPAP nasal foi titulado até a pressão de manutenção das vias aéreas superiores. A rota de fluxo do CPAP foi mudada de nasal para oronasal (n = 18) e oral (n = 16) durante o sono. A área retroglossal foi continuamente observada durante a nasoendoscopia. Resultados: O CPAP nasal (14,8 ± 4,1 cmH2O) foi suficiente para estabilizar a via aérea superior em todos os pacientes. Em contraste, o CPAP oronasal e oral promoveram eventos obstrutivos em 12 (66,7%) e 14 (87,5%) pacientes, respectivamente. Quando o CPAP foi transmitido pela rota oronasal e oral houve uma redução progressiva e significante na distância entre a epiglote e a base da língua e na área retroglossal em comparação com a respiração estável durante a rota nasal. Conclusões: Mudanças agudas na rota de fluxo do CPAP nasal para as rotas oronasal e oral induzem eventos obstrutivos e diminuem as dimensões da orofaringe em pacientes com AOS durante o sono. A máscara oronasal pode comprometer a efetividade do CPAP no tratamento da AOSIntroduction: Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for obstructive sleep apnea (OSA) and was conceived to be applied by nasal route only. However, in clinical practice the oronasal mask is commonly used. This study was designed to determine the acute effects of changing the nasal CPAP route to oronasal and oral in upper airway patency during sleep in patients with. We hypothesized that the pressure transmitted by the oral compartment of oronasal mask will push the tongue backwards and will compromise CPAP effectiveness in OSA treatment. Methods: Eighteen patients with OSA (age: 44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years44±9 years , body mass index: 33.8±4.733.8±4.733.8±4.7 33.8±4.7 33.8±4.7 Kg/m², apnea-hypopnea index: 49.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.149.0 ± 39.1 49.0 ± 39.149.0 ± 39.149.0 ± 39.1 events/hour) slept with a customized oronasal mask with a nasal and oral sealed compartments connected to a multidirectional valve. Sleep was monitored by full polysomnography and induced by low dosis of midazolam (3.1 ± 2.2 mg). Nasal CPAP was titrated up to holding pressure and flow route was changed to oronasal (n = 18) and oral route (n = 16) during sleep. Retroglossal area was continuously observed by nasoendoscopy. Results: Nasal CPAP (14.8±4.1 cmH2O) was able to stabilize breathing in all patients. In contrast, CPAP delivered by oronasal and oral route promoted obstructive events in 12 (66.7%) and 14 (87.5%) patients, respectively. Compared to stable breathing during nasal route, there was a significant and progressive reduction in the distance between epiglottis and tongue base and the retroglossal area when CPAP was delivered by oronasal and oral route, respectively. Conclusions: CPAP delivered by oronasal route may compromise CPAP effectiveness to treat OSA

Full textAbstract:
Introdução: As cavidades nasais constituem a via de acesso à hipófise na cirurgia transesfenoidal endoscópica. Deste modo, alterações naturais ou adquiridas da anatomia nasal podem prejudicar a cirurgia. Objetivos: Estudar as variações anatômicas das cavidades nasais, principalmente desvio do septo, correlacionando-as com a visibilidade no acesso transesfenoidal endoscópico, para subsidiar a decisão do tipo de acesso ou necessidade de correção do desvio. Material e Método: Estudo seccional em 38 pacientes submetidos ao acesso transesfenoidal endoscópico entre fevereiro de 2009 e janeiro de 2011 em centro de referência. No intraoperatório foram registradas as variações anatômicas, localização do desvio de septo no plano axial e coronal, largura do corredor cirúrgico, profundidade do acesso até o esfenoide e a sela, exposição do esfenoide e da sela após abertura dos mesmos. A dificuldade de visibilidade do acesso foi avaliada por escala ordinal: 0- sem dificuldade, 1- dificuldade leve a moderada, 2- dificuldade acentuada. Os testes empregados para correlação entre as variáveis foram qui-quadrado e razão de verossimilhança. A comparação entre duas médias foi pelo teste t de Student e três ou mais médias pela análise de variância (ANOVA), com teste complementar de Turkey. Resultados: Foram estudadas 76 cavidades nasais e foram observados 50 desvios septais (66%). A largura do corredor cirúrgico no local do desvio menor ou igual a 9 mm associou-se em 72% à dificuldade acentuada (p<0,001). Desvios de septo no andar médio (p=0,005) ou terço posterior (p<0,001) associaram-se à dificuldade acentuada. A largura da cavidade na região do desvio também foi menor no desvio do andar médio (8,41 mm, p=0,012) ou no desvio do terço posterior (6,9 mm, p<0,0001). No corredor cirúrgico, apenas a largura do meato médio se associou à dificuldade (5-13 mm, 73% dificuldade acentuada, p=0,001). Variações anatômicas das conchas foram observadas em 17%, sem impacto na visibilidade. O comprimento médio do septo nasal foi 64 mm (IC95%: 61,8-66,8 mm), a profundidade até o rostro do esfenoide 69 mm (IC95%: 67-71 mm) e até a sela 82 mm (IC 95%: 80,2- 83,8 mm). A exposição média do esfenoide foi de 20 mm (laterolateral) e 20,8mm (anteroposterior), enquanto da sela foi de 12,8 mm e 11,7 mm respectivamente. Conclusões: A largura da cavidade nasal na região do desvio e a presença de desvio de septo localizado em terço posterior ou no andar médio da cavidade nasal associaram-se à maior dificuldade na visibilidade do acesso transesfenoidalBackground: Nasal anatomical variations can impair the visibility on endoscopic transsphenoidal approach for pituitary tumors. Objective: To evaluate anatomical variations, mainly nasal septum deviation, and their impact on the visibility of transsphenoidal endoscopic approach. To support the decision of access type or need to correct the deviated septum. Methods: Cross-sectional study with 38 patients who underwent transsphenoidal endoscopic surgery using the two nostrils - four hands between February 2009 and January 2011 in a referral center. They were submitted to the intraoperative register of anatomical variations, septal deviations, surgical corridor width and location of the deviated septum (height and depth), depth of the access to sphenoid and sella, exposure of sphenoid and sella after opening. Visibility was assessed using an ordinal scale: 0- no difficulty, 1- low to moderate difficulty, 2- severe difficulty. Comparisons of two means were performed using Students t test, and three or more means using analysis of variance (ANOVA) with Turkeys complementary test. Correlations between scores were analyzed using the non-parametric chi-square test and the likelihood ratio. Results: Seventy-six nasal cavities were studied, and 50 septal deviations were found (66%). Among the patients with severe difficulty, 73% had a surgical corridor width in the location of the deviated septum of up to 9 mm (p < 0.001). Septal deviations in the middle level (p = 0.005) or posterior third (p < 0.001) were associated with severe difficulty. The width of the nasal cavity at the deviation was also smaller in the middle level (8.41 mm, p = 0,012) or posterior third (6.9 mm, p<0.001). In the surgical corridor, only the middle meatus was associated with difficulty (5 to 13 mm, 73% severe difficulty, p = 0.001). Anatomical variations of the nasal conchae were observed in 17% of cases with no impact on visibility. The average length of the nasal septum was 64 mm (95% CI 61.8 -66.8 mm); the mean depth to the sphenoid was 69 mm (95% CI 67-71 mm) and to the sella 82 mm (95% CI 80.2 - 83.8 mm). The average lateral exposure of the sphenoid was 20 mm and anteroposterior 20.8 mm and to the sella 12.8 mm and 11.7 mm respectively. Conclusions: The width of nasal cavity at deviation and site of septal deviation were associated with difficulty in visibility of the access. Septal deviations located at posterior third and at middle level in nasal cavities were strongly associated with difficulty

Full textAbstract:
Endoscopic nasal surgery is with minimal invasiveness for the surgical treatment of nasal disease. During traditional functional endoscopic sinus surgery (FESS), the surgeon uses one hand to hold the surgical instrument leaving the other hand to hold the endoscope. When the surgeon needs to use two hands to perform some complex procedure, an assistant surgeon is required to help holding the endoscope, and this requires good teamwork and long-time training. To solve this problem, researchers proposed to use robots to hold the endoscope, freeing the surgeon’s hands for bimanual operation. Sun developed a passive arm with pneumatic locking mechanism to hold the endoscope in FESS, but the surgeon needs to adjust the pose of the endoscope manually, which interrupts the surgery flow and lengthens the surgery time [1]. Many motor-driven endoscope holders have been proposed in literature [2], the surgeon interact with the robot with joystick, voice command, pedals or head movement [3–5]. However, there exists some drawbacks with these interacting methods, for example, joystick requires one of the surgeon’s hands, voice command is usually subject to interference and has long time-delay, foot pedals and head movement distract surgeon’s attention. Lin used a foot-attached IMU sensor to control an active robotic endoscopic holder, the inversion/eversion and abduction/adduction motions of foot are used to select and control different joints, but the motor can be only selected in order, which is unhandy for the four-joint scenario [6]. In this paper, a similar foot-attached IMU sensor is used, and the joints are selected in an easier manner, based on the angle of plantarflexion. Rather than the angle, the angular velocity of abduction/adduction is utilized to control the moving direction of the active joint. This paper describes the test result of the proposed control interface.

Full textAbstract:
Ingestible capsule endoscope technology has been a topic of research since the middle of the 20th century and has become a prominent area of study since the commercialization of capsule endoscopy in 2000. Ingestible telemetry capsules have been investigated by NASA in the last 20 years as a means for monitoring human body temperature during periods of physical exhaustion, but are limited in sensing time due to passage through the digestive system. In this work, we present a feasibility study on a sensor that attaches to the intestinal mucosa after being delivered to the bowel via ingestible capsule to be used on long distance space flights. This study included experiments conducted on NASA’s Weightless Wonder aircraft and replicated in a laboratory setting on the ground. During these experiments, a capsule was activated, manually inserted into excised porcine small intestine, and then automatically implanted a sham sensor onto the mucosal lining. The purpose of the experiment was to determine if the automated implantation sequence is affected by microgravity. Eight trials conducted in each setting yielded successful implantation of four sham sensors in microgravity and three in earth gravity. Results suggest that automated implantation is feasible in both 1G and microgravity environments though design changes are necessary to significantly improve repeatability in both environments. Though improvements in reliability of the device are needed, this experiment is a benchmark for transferring capsule technology currently used only for visual screening of the bowel to health monitoring systems for space flights.
